+/**
+ * @ngdoc directive
+ * @name ngAnimateChildren
+ * @restrict AE
+ * @element ANY
+ *
+ * @description
+ *
+ * ngAnimateChildren allows you to specify that children of this element should animate even if any
+ * of the children's parents are currently animating. By default, when an element has an active `enter`, `leave`, or `move`
+ * (structural) animation, child elements that also have an active structural animation are not animated.
+ *
+ * Note that even if `ngAnimateChildren` is set, no child animations will run when the parent element is removed from the DOM (`leave` animation).
+ *
+ *
+ * @param {string} ngAnimateChildren If the value is empty, `true` or `on`,
+ * then child animations are allowed. If the value is `false`, child animations are not allowed.
+ *
+ * @example
+ *
+
+ *
+ *
+ *
+ *
+ * ```
+ *
+ * Now, when the view changes (once the link is clicked), ngAnimate will examine the
+ * HTML contents to see if there is a match reference between any components in the view
+ * that is leaving and the view that is entering. It will scan both the view which is being
+ * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
+ * contain a matching ref value.
+ *
+ * The two images match since they share the same ref value. ngAnimate will now create a
+ * transport element (which is a clone of the first image element) and it will then attempt
+ * to animate to the position of the second image element in the next view. For the animation to
+ * work a special CSS class called `ng-anchor` will be added to the transported element.
+ *
+ * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
+ * ngAnimate will handle the entire transition for us as well as the addition and removal of
+ * any changes of CSS classes between the elements:
+ *
+ * ```css
+ * .banner.ng-anchor {
+ * /* this animation will last for 1 second since there are
+ * two phases to the animation (an `in` and an `out` phase) */
+ * transition:0.5s linear all;
+ * }
+ * ```
+ *
+ * We also **must** include animations for the views that are being entered and removed
+ * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
+ *
+ * ```css
+ * .view-animation.ng-enter, .view-animation.ng-leave {
+ * transition:0.5s linear all;
+ * position:fixed;
+ * left:0;
+ * top:0;
+ * width:100%;
+ * }
+ * .view-animation.ng-enter {
+ * transform:translateX(100%);
+ * }
+ * .view-animation.ng-leave,
+ * .view-animation.ng-enter.ng-enter-active {
+ * transform:translateX(0%);
+ * }
+ * .view-animation.ng-leave.ng-leave-active {
+ * transform:translateX(-100%);
+ * }
+ * ```
+ *
+ * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
+ * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
+ * from its origin. Once that animation is over then the `in` stage occurs which animates the
+ * element to its destination. The reason why there are two animations is to give enough time
+ * for the enter animation on the new element to be ready.
+ *
+ * The example above sets up a transition for both the in and out phases, but we can also target the out or
+ * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
+ *
+ * ```css
+ * .banner.ng-anchor-out {
+ * transition: 0.5s linear all;
+ *
+ * /* the scale will be applied during the out animation,
+ * but will be animated away when the in animation runs */
+ * transform: scale(1.2);
+ * }
+ *
+ * .banner.ng-anchor-in {
+ * transition: 1s linear all;
+ * }
+ * ```
+ *
+ *
+ *
+ *
